“…Sinus augmentation is generally considered a good method for edentulous maxillary posterior alveolar bone to allow an implant-supported prosthesis. Some modifications are available involving hydraulic elevation of the sinus floor via crestal approach (Vitkov et al, 2006) or outfracture of the lateral maxillary window (Lee, 2010). Evaluation of bone graft is based on the clinical evidence of fixture survival and functioning final prosthesis.…”

“…These limitations were overcome by modifying window opening method form inward to outward direction. Outfracture osteotomy sinus graft technique was introduced utilising readaptation of the outfractured bony window segment after sinus floor augmentation (Lee, 2010). It involves routine window opening on the lateral maxillary wall as in Fig.…”

Introduction: In the lateral window approach for a maxillary sinus bone graft, there has been considerable controversy regarding the placement of a barrier membrane over the osteotomy site. In particular, when there is no damage to the Schneiderian membrane, clinicians should decide whether to use a barrier membrane or not, considering the benefits and costs. This study presents the clinical cases to demonstrate that only repositioning the detached window can lead to satisfactory bony healing of the grafted material without using a barrier membrane in the lateral approach for a maxillary sinus bone graft. Materials and Methods:Five consecutive patients were treated with the same surgical procedures. After performing the antrostomy on the lateral maxillary wall using a round carbide bur and diamond bur, the bony window was detached by a gentle levering action. After confirming no perforation of the Schneiderian membrane, the grafting procedure was carried out the detached window of the lateral maxillary wall was repositioned over the grafted material without using a barrier membrane. A gross examination was carried out at the postoperative 6 month re-entry, and the the preoperative and postoperative dental computed tomography (CT) at re-entry were compared. Results: All the procedures in the 5 patients went on to uneventful healing with no complications associated with the bone graft. Satisfactory bone regeneration without the interference of fibrous tissue on the gap between the repositioned window and lateral wall of the maxillary sinus was observed in the postoperative 6 month re-entry. The CT findings at re-entry revealed the, reconstruction of the external cortical plate including repositioned bony window. In addition, the loss of the discontinuity of the lateral maxillary wall was confirmed. Conclusion:This preliminary report showed that the detached window, which was just repositioned on the grafted material, could function as a barrier membrane in the lateral approach for a maxillary sinus bone graft. Therefore additional morphometric and histologic studies will be needed.

“…The out-fracture osteotomy technique for sinus bone grafts, in which a complete 360-degree osteotomy, followed by bony window separation from the sinus membrane [10], has been used instead of the more common superior hinge or in-fracturing technique [1,11]. Kahnberg et al [12] demonstrated that, after release of the sinus mucosa, the bony window is fractured into the sinus cavity and subsequently forms a roof for the augmented sinus floor.…”

“…Kahnberg et al [12] demonstrated that, after release of the sinus mucosa, the bony window is fractured into the sinus cavity and subsequently forms a roof for the augmented sinus floor. The bony window has been used in some procedures to cover the grafted sinus in place of an absorbable barrier membrane [10]. In other procedures, the bony window has been crushed and mixed with the grafting material [13].…”

Aim The aim of this study was to evaluate the effect of using the lateral wall bone in sinus lifting two-dimensional reconstruction on bone augmentation. Patients and Methods Ten patients affected by class V or VI maxillary atrophy with less than 3 mm of residual horizontal ridge were selected. Using a piezo-ultrasonic surgery tip bony lateral wall was cut. To expose native bone to the bone graft, multiple perforations, made through the cortical plate of the recipient site with a round bur. Once the bony buccal wall was adjusted it was fixed away from the ridge with two 1.5 x 13 mm bone fixation screws. Deficiencies created between the bony buccal wall and the ridge was filled with a mineralized cortical bone. A pericardium membrane was then placed on the graft. A biopsy for histologic evaluation was made. Results The data analysis in bone volume changes reported significant differences between the anterior and posterior locations before and after grafting (p\0.05). The biopsy shows mature cancellous bone with predominantly lamellar structure. Conclusion The use of the lateral wall bone in sinus lift surgery showed significant increase in bone volume.
